Chula Vista  A 23-year-old man was killed and his older brother was arrested Tuesday morning after the two got into a fight at their Chula Vista home, police said.

Police were called to the Camelot of Eastlake condominium complex on Lakeridge Circle at 7:18 a.m. by a neighbor who heard someone screaming for help, police Capt. Gary Wedge said.

When officers arrived, they found Mario Gonzalez Figueroa lying on a bedroom floor suffering from what appeared to be several stab wounds to the upper body, Wedge said. He died at the scene.

His brother, Alberto Gonzalez Figueroa, 35, was arrested less than an hour later by National City police who spotted him near Sweetwater Road and Prospect Street.

Witnesses said they saw the older brother riding away from the complex on a red bicycle, with blood on his leg and on his clothes.

Neighbor Mitzi Ahkoi said she saw the man on the bike and thought he was suspicious because he kept looking behind him. She said she wondered what he was running from.

Another resident at the complex said she was walking her dog when she saw the suspect and said good morning to him. “He was nervous,” said Darnella Hosch. “He almost fell off his bike.”

She saw the blood on his clothes and thought he may have hurt someone.

When police arrived minutes later, her suspicions were confirmed. She described the man to officers who broadcast the description over the radio.

Wedge said the brothers lived at the condo with their mother and grandfather. The grandfather saw the two scuffling on the floor of the bedroom and was told to stay out of it, Wedge said. He ran to a neighbor’s and the resident called police.

Wedge said he did not know what precipitated the argument. He said police had been at the home twice before in recent months.

In December, officers were called after someone reported that a man at the condo was acting strange and was possibly under the influence of drugs. In January, they were called after someone reported that the brothers were fighting. When police arrived that day Gonzalez Figueroa was arrested after he assaulted one of the officers, Wedge said.

No murder weapon was immediately located, but police were still collecting evidence Tuesday at the home, he said.

Gonzalez Figueroa was taken to the Chula Vista police station for questioning, then booked into jail on a murder charge.
